Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] like Figure 1-4 As shown, this utility model provides a wire feeding machine, including a base 1 and a main unit 2. A fixed seat 3 and an AC motor 10 are fixedly connected to the upper surface of the base 1. A screw 4 is rotatably connected in a groove on the upper surface of the base 1. A movable seat 5 is threadedly connected to the outer surface of the screw 4. A fixing mechanism 7 is rotatably connected inside both the fixed seat 3 and the movable seat 5. A wire reel 8 is arranged between the two fixing mechanisms 7. A wire 9 is arranged on the outer surface of the wire reel 8 and extends into the interior of the main unit 2. The fixing mechanism 7 includes a rotating rod 701. A fixing plate 702 and a fixing sleeve 703 are fixedly connected to the outer surface of the rotating rod 701. A connecting rod 705 is fixedly connected to the outer surface of the fixing plate 702. A pressure plate 706 is fixedly connected to the end of the connecting rod 705. A push column 704 is threadedly connected to the outer surface of the rotating rod 701. An adjusting sleeve 708 is sleeved on the outer surface of the rotating rod 701.
[0021] Specifically, a first rotating wheel 11 is fixedly connected to the outer surface of the rotating rod 701, and a second rotating wheel 12 is fixedly connected to the output shaft of the AC motor 10. A belt 13 is provided on the outer surface of the first rotating wheel 11 and the second rotating wheel 12. The AC motor 10 drives the second rotating wheel 12 to rotate, and drives the first rotating wheel 11 and the rotating rod 701 fixed thereto to rotate through the belt 13, providing a power source for the wire feeding operation of the wire reel 8.
[0022] Specifically, the movable seat 5 is positioned opposite the fixed seat 3, and the fixing mechanism 7 is positioned on the opposite side of the fixed seat 3 and the movable seat 5. One end of the screw 4 is fixedly connected to a handwheel 6, which is located on the outside of the base 1. Rotating the handwheel 6 can drive the screw 4 to rotate, thereby causing the movable seat 5 to move along the direction of the screw 4 on the base 1, which facilitates the installation and removal of the coil 8.
[0023] Specifically, the outer surface of the rotating rod 701 is rotatably connected to the inside of the fixed seat 3 and the movable seat 5, the inside of the pressure plate 706 is fixedly connected to the outer surface of the fixed sleeve 703, the end of the push rod 704 away from the fixed sleeve 703 is fixedly connected to the handle 707, and one end of the adjusting sleeve 708 is rotatably connected to the end of the push rod 704 away from the handle 707. Rotating the handle 707 can push the push rod 704 to move, thereby driving the adjusting sleeve 708 to move.
[0024] Specifically, a support rod 710 is fitted inside the fixed sleeve 703. One end of the support rod 710 is fixedly connected to a push plate 711. The push plate 711 is located on the outside of the fixed sleeve 703. The support rod 710 moves along the guide groove 709 under the push of the adjusting sleeve 708, causing the push plate 711 to press against the inner surface of the coil 8, thereby achieving secondary fixation of the coil 8.
[0025] Specifically, the outer surface of the adjusting sleeve 708 is provided with a guide groove 709. The end of the support rod 710 away from the push plate 711 is slidably disposed inside the guide groove 709. The support rod 710 and the push plate 711 are disposed on the side of the pressure plate 706 away from the fixed plate 702. The guide groove 709 guides the sliding of the support rod 710, so that the support rod 710 can move smoothly in a predetermined direction, thereby pushing the push plate 711 to press against the coil 8.
[0026] The working principle of the above embodiments:
[0027] The method for calculating the reel diameter of this wire-feeding machine is as follows: based on the linear velocity of the main unit 2 and the angular velocity feedback of the wire-feeding inverter electrically connected to the AC motor 10, the angular velocity of the wire-feeding machine is calculated, and the diameter of the wire-feeding shaft can then be calculated. This calculation method eliminates the need for installing proximity switches or other sensors, accurately measures the diameter, and reduces the failure rate and hardware costs. Here, the linear velocity is V1, the angular velocity of the AC motor 10 is V2 = 6Of / p (where f is the known frequency of the inverter and p is the number of pole pairs of the motor), the reduction ratio of the wire-feeding motor is d1, and the diameter of the wire-feeding shaft is D. The calculation formula is V1 = (V2 / d1) * 3.14 * D. D can be calculated from this formula. The method for installing the wire reel 8 is as follows: rotating the handwheel 6 drives the screw 4 to rotate, causing the movable seat 5 to move along the direction of the screw 4 until the movable seat 5 moves away from the fixed seat 3 to a suitable distance for installing the wire reel 8. One end of the wire reel 8 is then inserted into the fixing mechanism 7 on the fixed seat 3, so that one end of the wire reel 8 is attached to the pressure plate of the fixing mechanism 7. On 706, rotate the handwheel 6 in the opposite direction to move the movable seat 5 closer to the spool 8 until the pressure plate 706 of the fixing mechanism 7 on the movable seat 5 presses against the other end of the spool 8, so that both ends of the spool 8 are clamped and fixed by the pressure plates 706 of the two fixing mechanisms 7. After the spool 8 is initially fixed, rotate the handle 707 to make the push column 704 rotate and move along the rotating rod 701. Since the push column 704 is rotatably connected to the adjusting sleeve 708, and the adjusting sleeve 708 is sleeved on the rotating rod 701, the adjusting sleeve 704... Driven by the push column 704, the spool 8 moves towards the inside of the fixed sleeve 703. Since the adjusting sleeve 708 is a transverse frustoconical shape with one end larger than the other, and the larger end is connected to the push column 704, the support rod 710 is pushed outward during the movement of the adjusting sleeve 708 until the support rod 710, along with the push plate 711, presses against the inner surface of the spool 8. With the support of multiple sets of support rods 710 and push plates 711, the spool 8 is fixed a second time, improving the stability of the device for installing the spool 8.
